The time period of revolution of geostationary satellite with respect to earth is
A
24 hrs
B
1 year
C
Infinity
D
Zero
Answer
Infinity
Explanation
Solution
From a non moving frame of reference, the time period of a geostationary satellite is 24 hours. But since, it is the same time for the Earth to complete one rotation, when seen from the earth the geostationary satellites look fixed at a point. In that way, the time period of a geostationary satellite with respect to earth is infinity.
